The BOC tank never dies. It's just that sometimes when people fill they decide to be clever and somehow pop an o-ring out of the fill rig, which is always easily remedied.I'll be bringing my dive tank (providing I get it in time, hopefully tomorrow), in case the BOC tank decides to die on us again.
Will confirm once I recieve it, it's on it's way to LiPS right now, should have it tomorrow.
